View Full Version : Ocau Needs You! Help Keep The Yanks At No. 2!

5th June 2005, 05:03 PM
Yes, that's right people.

The Folding@Home team of OCAU (http://www.overclockers.com.au), who have been on top of the Folding@Home ladder, needs some help at keeping [H]ardOCP at number 2 on the official stats.

(I've gotten the OK from Currawong to do this, so don't throw your arms up about this too much.. please.)

For those of you who know what Folding@Home is allready, you could probably skip the next couple of paragraphs.

Theres an easy to follow checklist in the second post.)

Folding@Home, (Link (http://folding.stanford.edu)) is a small program that, when open and running, sits there, and uses all of your idle CPU cycles. All versions (Windows, Mac, and Linux) are set to run at a very low priority, and so, any other program that needs CPU will get preference, and the preference change happens so fast you cannot (honest to god) notice it.

Those idle CPU cycles will be going to waste anyway, so, why not do something like this?

Basically, Folding@Home is a program that simulates the folding of proteins. I could rabble on about the details of it, but I don't have any sort of Science Degree, and I think that you would be much more likely to listen to the people who are in charge of Folding@Home, Stanford University. The details of proteins, and how they fold, can be found here (http://folding.stanford.edu/science.html).

So, since you've read this far, I'll assume that you are thinking about taking part. That's good! In order to take part, you'll need to download a FAH client, and they can be found here (http://folding.stanford.edu/download.html). The Mac clients can be found down the bottom. (Hey, don't shoot me, I didn't design the site!) I'd recommend getting the Text Console version, but that's just me. If you like seeing pretty colours, get the graphical version, and if you like seeing the pretty colours, AND you only want Folding@Home to run when you aren't using your computer, then get the Screensaver version.

I've never used the graphical and the screensaver versions, as not all of the spare CPU cycles will be spent on the actual folding process, as some will be used up rendering the pretty graphics. After you have downloaded and installed the client of your choice, and opened it up, it is time for you to choose your username and team number. (BTW, OCAU's team number is 24. Write that down, and remember it! :D)

After that, the client will connect to the internet, and download a Work Unit to start work on. This process normally takes anywhere between 15 and 40 hours, depending on the speed of your computer. After the Work Unit is done, it will automatically (if you are connected to the net) upload the results back to Stanford Uni, and then download another WU, and the process starts again!

On the advice of snax, I'll quickly sum it up into a checklist, but, it won't fit in this post, so check the one below. :)

Well, that should be everything you need to know.

Feel free to post any questions you may or may not have.

Cheers, Ultimata.

I just thought of something.

If anyone wanted, they could fold for ATAU, not as an actual team, but as a sub-team, under OCAU.

In order to do that (oh, and btw, a sub-team is simply a common username under which several people fold), you would, when you configure FAH, put ATAU as your username, and keep the team number as 24.

Ok, here is the checklist:

1) Download the FAh Client of your choice here. (http://folding.stanford.edu/download.html)
2) Extract to a folder on your Desktop.
3) Download InCrease here. (http://teammacosx.homeunix.com/forum/cgi-bin/ikonboard.pl?act=ST;f=10;t=172)
4) InCrease should, when opened, quickly scan for FAH folders, and thus, should have found the one on your Desktop.
5) Set, in InCrease, the username to be "ATAU" (without the quotes) and the team number to be 24.
6) Still in InCrease, make sure the tickboxes for -advmethods and -forceasm are ticked. (Just in case InCrease tells you, it's not recommended if you activate -advmethods if you have under 512 ram in total.)
7) If you have a dual (Lucky you!) then download and extract a second client, and go through the InCrease stuff again.

And there you are, Robert is your Mothers Brother.

Cheers, Ultimata.

Hi guys.

Well, thats good, I think at least a couple of you have started folding! http://folding.extremeoverclocking.com/use...php?s=&u=140914 (http://folding.extremeoverclocking.com/user_summary.php?s=&u=140914) :thumbup: At least my efforts wern't completely in vain.

I was just meaning to say that I completely forgot to say the way to get the bigger WU's for FAH, and the way to fold faster.

I have NFI how to do it for the GUI or the screensaver versions, but, for the CLI version, you simply start the program using the arguments '-forceasm' and '-advmethods'.

Oh, and if you want to make monitoring the GUI and the CLI versions easier, you can download a small program called InCrease, (found here. (http://teammacosx.homeunix.com/forum/cgi-bin/ikonboard.pl?act=ST;f=10;t=172)), which can let you enable all of the arguments really easily.

Oh, and another thing I forgot, if you are among the lucky ones who own a Dual G5, you can run two instances of the CLI client, and the other client will use the second CPU, but, this requires using the 'local' argument, which forces FAH to keep all of the work files it uses in the directory in which the program is kept, instead of in your /Library.

Cheers, Ultimata.

Oh, BTW, all for the arguments I stated up there, you drop the 's from around them.

Also, InCrease (which, BTW, I really recommend you get) auto set's up the arguments for you.

EDIT: Oh, and, guys, if you want to post any question, feel free, I won't bite. :)

happy to set it up on my G4 400mhz server running, but not always 100% in use. Just wondering if any info on bandwith use - just wondering for my limit :)

Each WU is only 2-3mb, so when you first connect, it will download a 2-3 WU, and then each consecutive time it finishes, you can expect a 2-3mb upload, and a 2-3mb download.

And with your server, I'd estimate that it would take around 4-5 days to do a WU that hasn't been recieved with the -advmethods tag, so, I'd estimate your total download for the month to be around 22-23mb, so, not really much at all. :D

Cheers, Ultimata
